Technical Passengers door wont lock

[Boostpt]

Hello.
I need a help.
When I lock the car from the remote, the passengers door sometimes doesn't lock. all the other doors lock fine.

I must go inside the car and press several times the lock and unlock button from the dashboard.
Then I try again to lock from the remote control, and then the door locks.

Can anyone help me to solve this problem?

Thanks

Maybe a sticky switch...........pull it out and clean the contacts?

Might help?

Clearly the lock is working if only intermittently
Something as simple as a bad connection may be to blame

Agree, could be poor connection as above. Or could be the lock needs lubrication. Connectors at the door hinge are common area for problems. Lock lubrication means door internal panel off.
